Two weeks ago I installed an antenna in my attic (GE 33692) in order to receive stations that are approximately 45 miles away. Things worked fine in clear weather, light rain and moderate snowfall but one morning there was dense fog and signal levels were lower across the board. Most stations still locked in but several didn't. The interesting thing was that all stations intermittently dropping out or pixelating were Hi-VHF channels.
I am wondering what the right fix for this is. Will a mast mounted pre-amp help or will a different type of antenna be the correct choice (perhaps a high gain Yagi?)? Unfortunately an outside antenna is out of the question for me.
